Dutasteride, Gyno and Estrogen

[Guest]

If I started Dutasteride, and monitored by blood results say every 3 months.. Would..

My estrogen levels rise if I was developing Gyno?

Is this best way to monitor side affects without relying on just symptoms?

So if my Estradiol levels remained the same, or very similar whilst on dutasteride.. Does this mean I won't develop any side affects such as Gyno?

Is Gyno a direct result of rising Estrogen?
